### Re: Circuit Lab B

1) Lenz's Law 2) Input resistance is infinite 3) R=p*L/A; Resistance= resistivity*length of wire/cross sectional area 4) Eddy Currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction Correct. Your turn t...

### Re: Circuit Lab B

Since no one is posting any questions: 1) Which law is analogous to Newton's Third Law and states that the direction of an induced current always opposes the magnetic field that produces it? 2) What is one assumption of an ideal operational amplifier? 3) Write the equation for the resistance of a wi...

### Re: Game On B

This is my first time doing this event and I was wondering other people's strategies for this event. My idea so far is to memorize the simple algorithms and stuff like that. I just wanted to know if others had a similar or different approach. Thanks This will be long. Blocks to Know|Move Turn Point...

### Re: Circuit Lab B/C

Does anyone have an idea of what types of electrical control devices we need to know about as explained in 3. c. vii.? I was wondering if we might need to know about switches, relays, and solenoids too. Also, I was wondering what everyone is doing to study for the simple measurements, constructions,...

### Re: Disease Detectives B/C

Asking questions a week before states yay 1). Should attack rate be in a percentage form? Should relative risk be in percentage form? Should odds ratio be in percentage form? 2). This was a question on a test: Number ill and exposed = 51, Number not ill and exposed = 34, Number ill and not exposed ...
